Application filed May 15, 1207. Serial No. 373,837.

to provide a fastener which permits the tire to be readily put on or taken off the wheel.

The invention comprises-a rim which is in two sections to one of which the tire is fastened and which is detachably connected to the othersection, the latter being permanently fastened to the felly of the wheel.

The invention also comprises novel means for securely fastening the rim-sections together and which permits their ready separation when desired.

In the accompanying drawings, Figure 1 is an elevation of a Wheel showing theapplication of the invention. Fi 2 is a crosssection .on the line 2-2 of Fig. 1. Fig. 3 is a cross-section on the line 33 of Fig. 1.

Fig. is a perspective view of a one of the rim-sections. Fig. 5 1s a perspectiveview of a portion of the other rimsection. Fig. 6 is an elevation of the clamping-ring hereinafter referred to. Fig. 7 is a detail of the connecting links of the clamping member hereinafter referred to. Fig. 8 is a vertical section, and Fig. 9 is an edge view thereof.

Referring specifically to the drawings, 10 denotes the usual wooden felly of the wheel. The rim which fastens the tire 11 to the felly is in two sections indicated at 12 and 13, respectively. The section 12 is permanently secured to the felly by means of bolts 14, or in any other suitable manner. The section 13 carries the tire and is detachably con nected to the section 12. At the edges of the section 13 are the usual tire-gripping flanges 15. The contiguous faces of the two sections are made slanting as clearly shown in Figs. 2 and 3 for a purpose to be hereinafter described. In one edge of the section 12 are notches 16 which are entered by projectionsl? on the section 13 adjacent one of its edges whereby the latter is prevented from creeping on the section 12. Adjacent its opposite edge the section 13 has a series-of slots 18, having beveled walls on portion of one side as indicated at 19. The other side walls are in line with the edge of the section 12.

The clamping member for fastening the two sections together comprises a flexible ring 20 having on its periphery a series of teeth 21 which are beveled on one 'side as indicated at 22 to'correspond to the bevel .19 of slots 18. The teeth are also made inclined or slanting at one end as indicated at 23. The ring is discontinuous being connected atits ends by a pair of links 2 1 by means of which the ring can be expanded and contracted.

In use, the ring 20 is placed on the edge of the section 12 with its teeth 21 extending into the slots 18. By reason of the slant of the contiguous faces of the sections 12 and 13 a pressure fit is had therebetween when the ring is in place, the bevels 19 and 22 serving to draw them tightly together, and

at the same time the slant. makes the re moval of the section 13 easy upon disengagement of the ring. By the inclines 23 the teeth 21 will force themselves out of the slots 18 when the rin is contracted. It will be noted that the inclines of one-half of the ring are oppositely presented to the inclines of the other half of the ring. The links 24 form a toggle and when straightened out they expand the ring to bring the teeth 21 into the slots 18, which locks the section 13 to the section 12. When the links are swung away from each other the ring contracts which withdraws the teeth from the slots which releases the section 13 and permits itto be removed.

The construction of the links 24 is clearly illustrated in Figs. 7 to 9. One of the links is forked as indicated at 25 and receives between its branches the reduced end 26 of the other link. The links are connected by a pivot joint 27. -On opposite sides of the reduced end 26 are longitudinal ribs 28, and on the inner sides of the branches 25 are longitudinal grooves 29. The parts are so arranged that when the links are expanded V to expand the ring 20, the ribs enter the grooves, whereby the links are securely held in expanded position. The forked link is made of spring metal so that when the links are contracted to contract the ring, the branches 25 spread to permit the ribs and grooves to separate. When the links are in expanded position as shown in Fig. 7 the 119 pivot 27' will be so located with respect to a straight line between the points at which the links are connected to the ends of the ring 20, that any pressure onthe links will be in a direction opposite to that tending to con tract the links, by reason of which the ring will not get loose accidentally. When in expanded position the links rest on the rimsection 12 thus relieving the ribs from all strain. One of the links is fitted with a re-.

movable operating lever 30.

The tirefastener herein described is especially advantageous for automobiles while touring or racing. The motorist can carry one of the rim-sections 13 attached to an extra tire all inflated, so that in case of damage to one of the tires, the damaged tire can be readily removed with its rim-section 13 replaced by the extra tire and its rim-section. Very little time will be lost as the change can be quickly made, the extra tire being already inflated.

The stem of the valve for inflating the tion 13 as heretofore described. The inner end of the valve-stem section 32 is reduced and threaded to screw into the threaded bore of the section 31. The outside of the valvestem sections is threaded'to receive a nut 33 which screws down over the joint between the sections. The nut is round and beveled on one side and seats in a recess in the rimsection 13 as shown in Fig. 3 so as to be flush with the inner surface of said rim-section.

The valve construction herein described enables the tire to be inflated when on the wheel and also when 'it is off the wheel. When the tire and rim-section 13 are removed the valve-stem sections must be separated which is readily done by unscrewing the section .32 from the section 31.v When the tire and rim section are ut on the wheel the valve-stem section will e connected by screwing them together. The the can then be inflated if necessary without removing it from the wheel.
